.SH NAME
mmcli \- Control and monitor the ModemManager

.SH SYNOPSIS
\fBmmcli\fR [\fIOPTION\fR...]

.SH DESCRIPTION
ModemManager is a DBus-powered Linux daemon which provides a unified
high level API for communicating with (mobile broadband) modems. It
acts as a standard RIL (Radio Interface Layer) and may be used by
different connection managers, like NetworkManager. Thanks to the
built-in plugin architecture, ModemManager talks to very different
kinds of modems with very different kinds of ports. In addition to the
standard AT serial ports, Qualcomm-based QCDM and QMI ports are also
supported.

.SH MANAGER OPTIONS
.TP
.B \-G, \-\-set\-logging=[ERR|WARN|INFO|DEBUG]
Set the logging level in ModemManager daemon. For debugging information you can supply \fBDEBUG\fR. Each value above \fBDEBUG\fR provides less detail. In most cases \fBERR\fR (for displaying errors) are the important messages.

The default mode is \fBERR\fR.
.TP
.B \-L, \-\-list\-modems
List available modems.
.TP
.B \-M, \-\-monitor\-modems
List available modems and monitor modems added or removed.
.TP
.B \-S, \-\-scan-modems
Scan for any potential new modems. This is only useful when expecting pure
RS232 modems, as they are not notified automatically by the kernel.

.SH COMMON OPTIONS
All options below take a \fBPATH\fR or \fBINDEX\fR argument. If no action is
provided, the default information about the modem, bearer, etc. is
shown instead.

The \fBPATH\fR and \fBINDEX\fR are created automatically when the
modem is plugged in. They can be found using \fBmmcli \-L\fR. This
produces something like (for modems only):

.RS 7
Found 1 modems:
  /org/freedesktop/ModemManager1/Modem/\fB4\fR
.RE

In this case, the \fBINDEX\fR is \fB4\fR and the \fBPATH\fR is the entire string above.

However, for the bearers, SIMs and SMS cases, the \fBPATH\fR is
slightly different. The \fIModem\fR is replaced with the object name
in use, like \fIBearer\fR. For example:

.RS 7
/org/freedesktop/ModemManager1/\fIBearer\fR/4
.RE

.TP
.B \-m, \-\-modem=[PATH|INDEX]
Specify a modem.
.TP
.B \-b, \-\-bearer=[PATH|INDEX]
Specify a bearer.
.TP
.B \-i, \-\-sim=[PATH|INDEX]
Specify a SIM card.
.TP
.B \-s, \-\-sms=[PATH|INDEX]
Specify an SMS.

.SH MODEM OPTIONS
All of the modem options below make use of the \fB\-\-modem\fR or
\fB\-m\fR switch to specify the modem to act on.

Some operations require a \fBMODE\fR. \fBMODE\fR can be any
combination of the modes actually supported by the modem. In the
perfect case, the following are possible:

.Bd -literal -compact
  \fB'2G'\fR  - 2G technologies, e.g. EDGE, CDMA1x
  \fB'3G'\fR  - 3G technologies, e.g. HSPA, EV-DO
  \fB'4G'\fR  - 4G technologies, e.g. LTE
  \fB'ANY'\fR - for all supported modes.
.Ed
.TP
.B \-w, \-\-monitor\-state
Monitor the state of a given modem.
.TP
.B \-e, \-\-enable
Enable a given modem.

This powers the antenna, starts the automatic registration process and
in general prepares the modem to be connected.
.TP
.B \-d, \-\-disable
Disable a given modem.

This disconnects the existing connection(s) for the modem and puts it
into a low power mode.
.TP
.B \-r, \-\-reset
Resets the modem to the settings it had when it was power cycled.
.TP
.B \-\-factory\-reset=CODE
Resets the modem to its original factory default settings.

The \fBCODE\fR provided is vendor specific. Without the correct vendor
code, it's unlikely this operation will succeed. This is not a common
user action.
.TP
.B \-\-command=COMMAND
Send an AT \fBCOMMAND\fR to the given modem. For example,
\fBCOMMAND\fR could be 'AT+GMM' to probe for phone model information. This
operation is only available when ModemManager is run in debug mode.
.TP
.B \-\-list\-bearers
List packet data bearers that are available for the given modem.
.TP
.B \-\-create\-bearer=['KEY1=VALUE1,KEY2=VALUE2,...']
Create a new packet data bearer for a given modem. The \fBKEY\fRs and
some \fBVALUE\fRs are listed below:
.RS 9

.TP
\fB'number'\fR
Telephone number to dial. Required in POTS.
.RE
.TP
.B \-\-delete\-bearer=PATH
Delete bearer from a given modem. This option explicitly uses a
\fBPATH\fR to define the bearer, you can not use an \fBINDEX\fR to be
deleted.
.TP
.B \-\-set\-allowed\-modes=[MODE1|MODE2|...]
Set allowed modes for a given modem. For possible modes, see the
beginning of this section.
.TP
.B \-\-set\-bands=[BAND1|BAND2|...]
Set bands to be used for a given modem. These are frequency ranges
the modem should use. There are quite a number of supported bands and
listing them all here would be quite extensive. For details, see the
MMModemBand documentation.

An example would be: 'egsm|dcs|pcs|g850' to select all the GSM
frequency bands.
.TP
.B \-\-set\-preferred\-mode=MODE
Set the preferred \fBMODE\fR for the given modem. The \fBMODE\fR
\fIMUST\fR be one of the allowed modes as set with the

.SH EXAMPLES
.SS Send the PIN to the SIM card

You'll need first to know which the proper path/index is for the SIM in your
modem:
.Bd -literal -compact
    $ mmcli -m 0 | grep SIM
    SIM | path: '/org/freedesktop/ModemManager1/SIM/0'
.Ed

And after that, you can just use the SIM index:
.Bd -literal -compact
    $ mmcli -i 0 --pin=1234
    successfully sent PIN code to the SIM
.Ed

.SS Simple connect and disconnect

You can launch the simple connection process like:
.Bd -literal -compact
    $ mmcli -m 0 --simple-connect="pin=1234,apn=internet"
    successfully connected the modem
.Ed

Then, you can disconnect it like:
.Bd -literal -compact
    $ mmcli -m 0 --simple-disconnect
    successfully disconnected all bearers in the modem
.Ed

.SS 3GPP network scan

Scanning for 3GPP networks may really take a long time, so a specific timeout
must be given:
.Bd -literal -compact
    $ mmcli -m 0 --3gpp-scan --timeout=300

    Found 4 networks:
    21404 - Yoigo (umts, available)
    21407 - Movistar (umts, current)
    21401 - vodafone ES (umts, forbidden)
    21403 - Orange (umts, forbidden)
.Ed

.SS Creating a new SMS message & storing it

Using the “sm” (SIM), you can do this using:

.Bd -literal -compact
    $ mmcli -m 0 --messaging-create-sms="text='Hello world',number='+1234567890'"
    Successfully created new SMS:
        /org/freedesktop/ModemManager1/SMS/21 (unknown)

    $ sudo mmcli -s 21 --store-in-storage="sm"
    successfully stored the SMS

    $ sudo mmcli -s 21
    SMS '/org/freedesktop/ModemManager1/SMS/21'
      -----------------------------------
      Content    |              number: '+1234567890'
                 |                text: 'Hello world'
      -----------------------------------
      Properties |            PDU type: 'submit'
                 |               state: 'stored'
                 |                smsc: 'unknown'
                 |            validity: '0'
                 |               class: '0'
                 |             storage: 'sm'
                 |     delivery report: 'not requested'
                 |   message reference: '0'

    $ sudo mmcli -m 0 --messaging-status
    /org/freedesktop/ModemManager1/Modem/0
      ----------------------------
      Messaging | supported storages: 'sm, me'
                |    default storage: 'me'
.Ed

.SS Sending SMS messages from files

As you can see below, the important part is the
\fB\-\-messaging\-create\-sms\-with\-data\fR and the \fBPATH\fR provided.

.Bd -literal -compact
    $ sudo mmcli -m 0 \\
           --messaging-create-sms="number='+1234567890'" \\
           --messaging-create-sms-with-data=/path/to/your/file
    Successfully created new SMS:
        /org/freedesktop/ModemManager1/SMS/22 (unknown)

    $ sudo mmcli -s 22 --send
    successfully sent the SMS
.Ed

.SS Listing SMS messages

When the receiver gets all the parts of the message, they can now
recover the sent file with another \fBmmcli\fR command in their
ModemManager setup:

.Bd -literal -compact
    $> sudo mmcli -m 0 --messaging-list-sms
    Found 1 SMS messages:
        /org/freedesktop/ModemManager1/SMS/0 (received)

    $> sudo mmcli -s 0 --create-file-with-data=/path/to/the/output/file
.Ed

.SS GPS location status

You first need to check whether the modem has GPS-specific location
capabilities. Note that we’ll assume the modem is exposed as index 0;
if you have more than one modem, just use --list-modems to check the
proper modem index:

.Bd -literal -compact
    $ mmcli -m 0 --location-status
    /org/freedesktop/ModemManager1/Modem/0
      ----------------------------
      Location | capabilities: '3gpp-lac-ci, gps-raw, gps-nmea'
               |      enabled: 'none'
               |      signals: 'no'
.Ed

The output says that the modem supports 3GPP Location area code/Cell
ID, GPS raw and GPS-NMEA location sources. None is enabled yet, as we
didn’t enable the modem, which we can do issuing:

.Bd -literal -compact
    $ sudo mmcli -m 0 --enable
    successfully enabled the modem

    $ mmcli -m 0 --location-status
    /org/freedesktop/ModemManager1/Modem/0
      ----------------------------
      Location | capabilities: '3gpp-lac-ci, gps-raw, gps-nmea'
               |      enabled: '3gpp-lac-ci'
               |      signals: 'no'
.Ed

.SS GPS location technology enabling

We can enable the RAW and NMEA GPS location sources using:

.Bd -literal -compact
    $ sudo mmcli -m 0 \\
                 --location-enable-gps-raw \\
                 --location-enable-gps-nmea
    successfully setup location gathering
.Ed

If we do check again the status, we’ll see the GPS-specific locations are enabled:

.Bd -literal -compact
    $ mmcli -m 0 --location-status
    /org/freedesktop/ModemManager1/Modem/0
      ----------------------------
      Location | capabilities: '3gpp-lac-ci, gps-raw, gps-nmea'
               |      enabled: '3gpp-lac-ci, gps-raw, gps-nmea'
               |      signals: 'no'
.Ed

.SS GPS location retrieval

You can query location source specific information with
\fB\-\-location\-get\-3gpp\fR, \fB\-\-location\-get\-gps\-nmea\fR and
\fB\-\-location\-get\-gps\-raw\fR; but also for all at the same time:

.Bd -literal -compact
    $ sudo mmcli -m 0 --location-get
